#136 – a leading ID proponent rebuts our anti-ID challenges

After last week’s scientific experts cleared up much ID-rhetoric, we ask a rising star in the ID movement — Dr. Jonathan McLatchie — to respond to our reinvigorated questions, concern, and critiques of Intelligent Design After starting this mini-series with an interview with one leading ID proponent, and then hearing from a number of scientific experts who gave a different perspective on things, we now want to finish this on-going conversation with an interview with another leading ID proponent — a relatively new face — Dr. Jonathan McLatchie. With three graduate degrees in biology and evolutionary biology, he may be a rising leader in that movement. Before the interview, we gave him a list of the anti-ID challenges we’d be raising, so that we could get fully prepared and informed responses to those questions. Here are his answers, and our other points of discussion: Challenge #1: for us, ID is still just God-of-the-gaps thinking Challenge #2: ID doesn’t explain anything, it just attributes phenomena to an intelligence without saying anything about exactly how that intelligence might have done it. ID proponents often refer to this as an inference to the best explanation, but is it really just an inference to the best attribution? Challenge #3: where does the science go after the attribution has been established? Does ID make testable predictions which actually advance scientific knowledge? as always happens in discussions with ID proponents, “junk DNA” came up as one of ID’s greatest scientific advances Challenge #4: ID proponents often make reference to astronomically huge numbers when refuting evolutionists (“the chances of that happening spontaneously are one in 10 with eighty-nine zeroes behind it“) …. again, this just betrays God-of-the-gaps thinking Challenge #5: ID proponents are always attacking “Darwinism.” We need to move away from simple Darwinian mechanisms and recognize that genetics has moved far, far beyond simple point mutations; we now know about large-scale movements and reorganizations of DNA what exactly does “Darwinism” mean to an ID proponent? we started to wade a bit into the evo/devo world (a term for evolutionary developmental biology, which pertains to how a single-celled embryo organizes itself into a multi-cellular fetus) Challenge #6: ID proponents often resort to hyperbolic appeals to “cataclysmic failure” and “death” and “extinction” in order to push back on discussions of genetic mutations and rearrangements being the creative engine of evolution; they only see genetic changes as harming a given protein/function, and avoid or ignore the possibility that a genetic change might morph that function into a new one (a process referred to as exaptation) gene duplication with modification is the R&D department of the cell as ID proponents often do, Dr. McLatchie quoted from a small select group of scientific studies which supported his pro-ID or anti-evolution point(s), while not accounting for the much larger number of scientific papers which come to the opposite conclusions (“cherry-picking”) Dr. McLatchie claimed that there is very little evidence of gene duplication and modification producing new functions; we countered with one example of the family of receptors that convey smell (there are thousands of these, all just a little bit different from each other), but didn’t have time to talk about visual receptors, ion channels, protein-eating enzymes, carbohydrate-eating enzymes, neurotransmitter receptors, signaling molecules called GPCRs, antibodies, ………… the list goes on and on ID proponents re-defining the adjectives “detrimental” and “beneficial” when talking about genetic mutations disparaging misrepresentations of the Long-Term Evolution Experiment; we will be talking to one of the members of that project in the next few weeks to fact-check statements from Dr. McLatchie (in this episode), Dr. Behe a few weeks ago, and from ID proponents in general Dr. McLatchie sees evolutionary mechanisms simply “degrading genetic information,” while we see this as life getting creative and trying new things, and re-purposing old ideas function becomes conflated with design; just because something has a function, this doesn’t mean it was “designed” to do that (did someone “design” an old broken brick to hold that garage door open?) strange/awkward designs (backwards wiring of the retina) and truly malevolent designs (convergence of the wind-pipe and food-pipe, or childbirth) make it hard for many of us to embrace ID; a designer working from the bottom up wouldn’t design it this way when asked why humans couldn’t have been “designed” with thicker necks having a food pipe on one side completely separate from a windpipe on the other side, the response can’t be “well, that would look weird” the accumulation of gradual changes that we see in living organisms over time (complete with genetic dead-ends and fragments of old, out-dated designs) is not consistent with the idea of a Master Designer what do ID proponents think of common descent of humans and primates (they’re quite divided on this), and how exactly do they explain speciation? why is the scientific community at large so resistant to ID-thinking? the ancient Hebrews thought the weather involved God having jars of rain, closets of lightning bolts, and breathing out the wind and the dew; today, we can set up mathematical models that only take into account gradients of temperature, pressure and humidity and predict the weather out over the next week or two exactly how would “the Designer” design things? What would this look like? Is he/she/it tirelessly tinkering away at a work-bench, or just dropping in from time to time to nudge things over key evolutionary hurdles? Jonathan’s answer included a reference to periodic injection of information content into the global pool of living organisms (“the biosphere”) As always, tell us your thoughts on this topic … Find more about Dr. Jonathan McLatchie, including upcoming public speaking engagements and writings, at his web-site.

#135 – The expert’s fascinating version of how the flagellum really came to be

Three internationally-recognized, world experts on the bacterial flagellum connect the dots regarding the evolutionary origin of the flagellum, and draw some compelling comparisons to the evolutionary emergence of the Bible! Three episodes ago, Dr. Michael Behe used the bacterial flagellum as Exhibit A in his defense of the Intelligent Design proposal. Last week, we heard Dr. Nicholas Matzke, who actually does cutting edge research on the flagellum, give his understanding of the bacterial flagellum, with comparisons to claims frequently made by the ID community. In this episode, we hear three world-leading scientific experts on the flagellum discussing the latest scientific data on an amazing evolutionary journey which seems to explain the origin of the flagellum. Those three are Drs. Matthew Baker (University of New South Wales, Australia), Mark Pallen (University of East Anglia, UK), and Nick Matzke (University of Aukland, New Zealand). Some of the technical points they discussed include: how to make direct measurements of individual flagellum motors freshly isolated from a test tube of bacteria why is there so much interest in the bacterial flagellum ….. why have so many researchers using such high-tech equipment studied this thing? the flagellum is not just one unchangeable thing (as ID proponents will often suggest); instead, the broad scientific community agrees that there are MANY different kinds of bacterial flagella (hundreds of thousands), each with different genetic sequences, and some of which seem to be missing parts, and yet still work for their hosts at the heart of two bacterial nanomachines there is a third nanomachine called “the type III secretion system” whose function is to squirt out proteins; the one in the flagellum squirts out the proteins that make the long propellor whip, while the one in “the injectosome” squirts out the toxins that the bacteria uses to capture its prey these are two examples of machines built on top of machines – Mark referred to it as “a modular system” there is yet another bacterial nanomachine — “the “ATP-synthase” — whose function it is to generate energy molecules called ATP; given how fundamental this function is, ATP-synthase is probably one of the oldest of cellular machines there are many striking similarities (genetic; structural; functional) between ATP-synthase and the type III secretory system, which suggests a common ancestral origin; in other words, those two very different enzymes seem to have both descended from yet another earlier enzymatic precursor there is some reason to suggest that the precursor for the type III secretory system (and for ATP-synthase) might have been related to one that modifies RNA, an enzyme called RNA-helicase; one of those reasons is the fact that all three are made up of six globular proteins that form a ring wrapped around a central filament of protein (in the case of the type III secretory system) or a filament of RNA (in the case of RNA-helicase), and all three spin like rotary motors as they do their job the type III secretory system is NOT a devolved bacterial flagellum (as ID proponents will often claim) Altogether, the evidence starts to point to a possible scenario involving a recurring theme of gene duplication with subsequent modification of the copies, followed by selection for a useful function: an ancient primordial gene for an enzyme that comprised a rotary motor that spins around some filament was duplicated those two primordial gene copies morphed and diverged such that one specialized for RNA (the helicase) and the other specialized for proteins (becoming a generic protein pump) somewhere in that transition, one of those two new genes duplicated, and the resulting copy started to code for a rotary engine that ran in reverse and latched onto a protein to drive it to generate ATP (ATP synthase) the gene for the generic protein pump was duplicated and the copies began to specialize for pumping certain subsets of proteins … one for flagellar proteins (thereby becoming a propellor, the bacterial flagellum) …. and the other one for toxins (thereby becoming a weapon, the injectosome) Parts of this story are more speculative than others, but the emerging picture is looking quite clear that the bacterial flagellum is the product of a long evolutionary journey. That hypothesis then prompts new research questions which flesh out the details of this evolutionary journey. There was an extended conversation about how genes/proteins can change/morph over time and take on entirely new functions …. and how this phenomenon is precisely paralleled by the evolution of language (the words loyal, legal, and lawful all have a common ancestral origin), and even of the Bible itself! I asked our guests to comment on Michael Behe’s claim that secular scientists themselves are doing the scientific work of Intelligent Design by “doing their experiments from a Design perspective without calling it that.” Admittedly, it’s pretty hard for scientists to say anything about evolution without using wording such as “this protein/trait is designed to enable the animal to XYZ” or “this organism evolved toward being able to XYZ.” This is goal-oriented language … wording that conveys purpose, meaning, direction, guidance … otherwise known as “teleological” language. One response to this assertion was that it can also be “sloppy language,” just like humans have the tendency to refer to Earth as “her” or to a truck as “him.” I also asked our guests if it is possible to meet the ID proponents in the middle by saying that there is indeed “a designer”, but that designer is the cell itself (which orchestrates the genetic changes) and evolutionary pressures (which select out the good stuff). One guest replied provocatively, but entirely legitimately, that if ID proponents insist on personifying “the designer” by referring to him/her/it as intelligent, then how do they explain the flagellum being so well designed to move the bacterium around through the human host’s body in order to mediate such nasty, devastating, destructive disease outcomes. Interesting conversation indeed! As always, tell us your thoughts on this topic … Find more information about our guests at Nicholas Matzke’s profile, Mark Pallen’s profile, and Matthew Baker’s profile.

#134 – The bacterial flagellum according to an expert

A scientist who specifically studies the bacterial flagellum using some of the most cutting-edge research tools clears up a few myths and misconceptions. Much of Dr. Michael Behe’s defense of Intelligent Design rests on claims made about the bacterial flagellum. It certainly has become his signature, and one could even say it’s become the symbol or mascot of the ID movement (like the polar bear became for the global warming movement). Some of his claims are often challenged by opponents of ID. To shed some light on the subject, we reached out to several scientists who actually work with the bacterial flagellum (Behe does not). Here, we speak to Dr. Nicholas Mitzke, who gives us a basic introduction to this bacterial machine, demystifying it and clearing up some misconceptions that have been built up around it. Points that we discussed included: misconception #1: the flagellum is not just one unique thing that cannot be altered in any way without completely losing its function. There are in fact thousands of different versions of the flagellum, each with differences in their amino acid sequence (which necessarily means their gene sequence was changed), and some of them are even missing certain protein parts, and yet all of these altered versions retain their function. misconception #2: the flagellum did not in fact arise through a series of intermediate steps, each intermediate being non-functional, before finally becoming a functional machine. Instead, we’re now getting glimpses of its evolutionary journey through various stages of different functionality. proteins in general can evolve, changing amino acid sequences in many ways, and yet retain their original shape, and therefore full function how the rotary engine in the flagellum converts chemical energy into a rotational movement; it uses an acid battery that spins an “electric” rotor the flagellum is made of multiple copies of 20 proteins; 99% of the flagellum is the long whip (tens of thousands of copies of one particular protein); the other 19 proteins are at the base of the flagellum, forming one machine that creates the flagellum (the “type III secretion system”) and another machine that rotates the flagellum (the motor). misconception #3: given the statement above, the type III secretion system is NOT a “devolved” flagellum misconception #4: cellular machines (like the flagellum) do not need a mechanic to assemble the different parts into a functional machine (a misconception based on our familiarity with human-made machines). Instead, cellular machines can make themselves!? Self assembly!!! [we talked about this in detail in episode #131] misconception #5: the flagellum motor does not work through pistons, gears, fan-belts, and other such moving parts (as might be misconstrued by the frequent references to the flagellum being “like the outboard engine of a boat”). Instead, they work through a series of simple shape-shifts … the protein parts just bend a bit this way or that, causing other subtle shape-shifts in their neighbors. we introduced another bacterial machine called the ATP-synthase, because this will become a key star in next week’s episode about the evolutionary origin story of the flagellum. It’s basically two small machines combined into one: an ion pump, and an energy molecule factory. we heard a very condensed version of that evolutionary origin story, one that links three very different bacterial machines (the type III secretion system, ATP synthase, and the flagellum), in order to whet listener’s appetite for next week’s episode. This story is very much like someone encountering a complete stranger, noticing some absolutely striking resemblances in facial features, and finding out that the stranger is a cousin/sibling they never knew about. As always, tell us your thoughts on this topic. To learn more about our guest expert, visit his faculty profile page. If you enjoyed this episode, make sure you’ve listened to our interview with Michael Behe (or listen to it again, now that you’ve been informed). Also, if you haven’t already heard the other episodes in this mini-series, you might benefit from our basic introductions to how genes and proteins work. Episode image by Raman Oza from Pixabay.

#133 – Five things you probably misunderstood about genetics

Most people don’t know: the genome is a formatted database with read/write memory systems which can reorganize itself to produce new species. This is a re-release of an episode we put out almost two years ago. In the episode that preceded this re-release, and which set the stage for this interview, we had given a thumbnail sketch of genetics as most people understand it. We distilled that common understanding into five basic statements, and showed how most people think new species (or new cellular machines, like flagella) somehow arise from genetic mistakes and accidents. And we said we would be talking to Dr. James Shapiro, a world-leading geneticist with 60 years of experience in the field and who co-leads a large group of world-leading scientists working to correct this fundamental misunderstanding of genetics and evolution, in order to fact-check that common understanding. It turns out, it’s not just outdated, but deceptively wrong! Here’s what he told us about those five basic statements. Fasten your seat belts! (1) it’s all about DNA: who you and your children are is all completely determined by your DNA; Your brain cells, muscle cells, blood cells … and all the other cells of your body … have exactly the same DNA; and yet they’re so very unique in many ways! What makes them different from each other — and you from anybody else — is determined largely by another molecule: RNA. (2) DNA is a long molecule which gathers together many genes, like beads on a string, which code for the proteins that your body is made of; Only a very small fraction of your genome (the total collection of all your genetic material) codes for proteins; just a few percent in fact. Most of the rest of your DNA codes for RNA molecules which regulate the entire genetic machine. Also, any given “gene” (discrete chunk of information) is not like one of those beads on the string: instead, it has bits and pieces scattered all over your genome. (3) cells do everything they can to protect those genes from any kind of change; In fact, your cells have built-in mechanisms which do the exact opposite of that: they actively change the organization of your DNA, in response to evolutionary pressures, by: – moving large chunks from one position to another, even between chromosomes (recombination and reorganization); – moving large chunks between completely different species (“horizontal transmission”, in contrast to the standard “vertical transmission” from your parents); – combining the genomes of two different related species to produce a new third species (hybridization) or produce an entirely different kind of organism (the origin of the mitochondria and chloroplast); (4) UV light and mutagenic chemicals cause random mutations in the DNA, which can alter the function of the proteins they encode; Cells have very good error-correcting mechanisms which undo those kinds of mistakes, as well as those made when the “photocopier” (the DNA-duplicating machine) goes on the fritz; (5) those random mutations accumulate over time, producing individuals with new characteristics (e.g., blood type; hair color) and eventually … a new species; The occasional random mutations which might make it through the error-correcting mechanisms referred to in #4 above are completely unable to explain the origin of major changes in a given species (new “phenotypes”), let alone the origin of entirely new species. How much more wrong could we have been? This new and improved understanding of genetics and biological evolution opens up new ways to defuse the debates which keep coming up when creationists push back on the Theory of Evolution. Or on the evolutionary origin of the bacterial flagellum! As always, tell us what you think … If you want to hear our summary of the common [mis]understanding of genetics, and the backdrop for this interview, check out Episode #69. As a bonus, that episode also explored nine reasons why some people push back on the whole idea of evolution (in some cases, because they just don’t properly understand genetics and evolution).

#132 – Intelligent Design and the bacterial flagellum

Dr. Michael Behe, a biochemist and Intelligent Design proponent, gives us his perspective of ID, and responses to several counterarguments against ID. To start off our deep-dive into Intelligent Design, we wanted to talk to a knowledgeable representative of that movement. Dr. Michael Behe, a biochemist who has been waving that flag for three decades now, and Senior Fellow at the Discovery Institute (“ID Headquarters”), was a great choice for this first conversation. In addition to exploring a variety of biochemical and physiological concepts, our main goal was to get his response to several counterarguments against Intelligent Design which we hear often (and resonate with). Our points of discussion included: he’s not a Young Earth Creationist … he does accept human evolution from an ancestor we share in common with the apes; as an Intelligent Design proponent, he believes that the evolutionary steps had to have been guided (not random or undirected) “irreducible complexity” refers to a system/machine which has multiple parts and requires ALL of those parts to maintain its original function [our response: “sure, but it CAN be changed or reduced to do other functions”] his often-used analogy for irreducible complexity is a mouse-trap cells are made up of nanomachines which are made out of many parts, all of which are essential or the machine no longer works (“so they’re irreducibly complex”); his often-used example is the bacterial flagellum motor (BFM) he argues that this irreducible complexity can not be accounted for by Darwinian mechanisms counterargument #1: you can indeed take away certain parts, and what remains can still be quite functional, albeit perhaps not as a flagellum motor (or mousetrap). The BFM can be stripped down to a much smaller number of parts leaving another bacterial machine (the type III secretory system) which has a completely different function (it’s involved in squirting proteins out of the cell, rather than in giving the cell mobility). Also, many of the individual parts of the BFM can serve other functions on their own. counterargument #2: ID proponents tend to limit the discussion to “Darwinian” evolutionary mechanisms — random, undirected mutations of single base pairs — and avoid a more modern understanding of genetics which includes large-scale genetic changes which are orchestrated by the cell (duplication; reorganization; shuffling of whole sections of DNA; recombination; horizontal gene transfer; epigenetic changes) counterargument #3: if we’re going to attribute changes to a Designer, what do we do about examples of bad design (not just strange or clunky design …. but actually horrible design which produces indiscriminate suffering and death) counterargument #4: ID is not science. It doesn’t propose hypotheses that can be tested. It doesn’t explain the phenomenon (the mutation or new genetic trait), it only attributes the phenomenon to a Designer who worked in a mysterious way that we might never understand and for reasons that we can’t see counterargument #5: ID is more religion than science, and forces people to choose between the two (in a zero-sum fashion) there is another entirely different bacterial nanomachine called ATP-synthase which has jaw-dropping genetic and structural similarity to the type III secretory system at the heart of the BFM, but has yet another completely different function (it makes energy molecules, rather than squirt out proteins or give the cell mobility). This similarity might give clues regarding the evolutionary origin of the BFM. We’re going to get into this in much more detail in a couple weeks with experts in this area As always, tell us your thoughts on this topic … If you haven’t already heard the two episodes that preceded this one (Episode #130 and #131), you really should: they’re all part of a mini-series we’re doing on Intelligent Design, and they set the stage for this one. You may also like Episode #70, where we talked to Dr. James Shapiro (an Emeritus professor with decades of hands-on experience with genetics at several world-renowned universities) about how cells routinely move large chunks of DNA around.

#131 – Cell Biology 101 (essential background for ID talks)

Before hearing from Intelligent Design advocates, we thought we’d give our listeners some useful background information about how cells work …. it turns out it’s all about making shapes out of string. Before we present our interviews with Drs. Michael Behe and Jonathan McLatchie (both leading proponents of Intelligent Design), we feel we should give our listeners a quick Cell Biology 101 to explain some of the concepts that will frequently come up in those interviews, and which easily mislead non-experts. So, in this episode we’ll talk about how cells make proteins, and how it’s the sequence of amino acids (which is directly decoded from the gene sequences) which determines the 3-dimensional (3D) shape of the protein, and that in turn gives the protein its functionality. In this casual conversation, given at a NON-EXPERT level, Scott and I talked about: the string of DNA gets decoded into a long string of amino acids (we came up with two metaphors for this long string: toothpaste being squeezed out of a tube, and “Silly String” being squirted from an aerosol can at a party) that string of amino acid is called a protein; protein adopts a 3D shape that directly gives it its functionality the toothpaste / Silly String forms a long strand which flops all over itself, forming loops and folds and a completely disorganized mess; the strand of protein would also form a disorganized mess, except for the fact that the amino acids themselves begin to interact with each other and generate attractive/repulsive forces that cause it to fold and compact the loops into a particular 3D shape force #1: electrostatic attraction … a series of positive and negative charges which strongly attract each other, kind of like a sock sticking to a towel when you pull them out of the dryer, and have to peel the sock off force #2: electrostatic repulsion … a series of positive versus positive charges (or negative versus negative charges) which push each other apart, kind of like your hair standing on its end when you put your hand on a van de Graf generator at a science museum force #3: hydrophilic/hydrophobic attraction … a series of “water-loving” amino acids want to stick together (like sticking a piece of paper to a window just by making it wet); in the same way, “water-hating” amino acids want to stick together force #4: hydrophilic/hydrophobic repulsion … a series of “water-loving” amino acids and “water-hating” amino acids push away from each other (like oil and water not wanting to mix) force #5: atomic bond sharing … two amino acids both grabbing on to a hydrogen (like two people fighting over a trophy) or both becoming physically connected to a shared sulfur atom (like two people being hand-cuffed together) force #6: peg-and-socket connections …. groups of amino acids clumping together like a ball, and then inserting themselves into another group of amino acids which have formed into a doughnut shape (like buttoning up your shirt, or putting a jigsaw puzzle together) force #7: each type of amino acid holds its two arms out at different angles (both forward; or one backward and other forward; or both at 90 degrees from forward [or 60 degrees, or 45 degrees, or ….]), and as you connect these different types together (by getting them to hold hands), the angles of their arms begins to make the straight strand of protein kink up and loop in certain predictable ways we discussed how the sequence of the amino acids in the protein uses these forces and interactions to constrain the protein strand into specific and predictable 3D shapes, like: filaments, poles, tubes, beams, sheets, planks, pegs and sockets, and other shapes we did a mental exercise of creating a screw or a bolt using these forces and interactions, and also building an ion channel that you might find in a nerve cell! other intricate, complex and beautiful things can also be explained by naturalistic mechanisms: the Grand Canyon was created by simple geochemical and geophysical forces, or the beauty of a sunset against a stormy sky with a rainbow off to the side is mathematically explained by optical physics and gradients of air pressure, temperature and humidity reducing such complicated cell biology to “just chemistry and physics” doesn’t need to diminish “the Creator,” any more than showing that Leonardo DaVinci is “only” working with simple paints and a stick/brush; one is still free to invoke a Creator … or to deny the same. this raised questions about teleology and the processes being goal-directed, and science tending to be too reductionist a second VERY important topic we discussed was how these inanimate protein parts can self-assemble. Yes: SELF-ASSEMBLY! It sounds like magic, but it’s a common feature in cell systems, and it’s relatively easy to explain (we did this by having Scott jiggle a drawer full of spoons). No need for a little technician with a screw-driver and hammer in hand to put those parts together and a third VERY important topic: changes in the genetic information do not have to be simply a single change at one point in the strand of DNA or one single amino acid at a time (as YEC and ID advocates want listeners to believe). Instead, cells will commonly move and reorganize large segments of DNA at a time, coming up with entirely new combinations, which in turn leads to new genes. duplication (of parts of genes, of whole genes, or even of whole chromosomes!) accounts for the problem that YEC and ID advocates frequently raise: the original copy can still fully take care of the originally intended cell function, while the duplicated copy can go on to enhance its function, or even become adapted for a completely new purpose. Yes, you CAN have your cake and eat it too! duplication and re-shuffling of genetic information explains the evolution of proteins (we showed how easy it is to change a spoon/shovel into a knife/axe, or a stiletto/poker, a fork, a hammer). The immune system routinely takes this shuffling/re-building to a whole new level. coaptation: a protein can remain intact and serve more than one function, even in entirely different systems, or it can be slightly modified to now serve a new function As always, tell us your thoughts on this topic … If you enjoyed this episode and/or if you want to learn more about the genetic aspects of this discussion, you should check out Episode #70, where we talked to Dr. James Shapiro (an Emeritus professor with decades of hands-on experience with genetics at several world-renowned universities) about how cells routinely move large chunks of DNA around.

#130 – Intelligent Design – an introduction

A short introduction to start a mini-series on this Christian apologetic idea, and some of the reasons why we have such difficulty with it. Intelligent Design” has attracted much criticism — certainly from the secular, scientific community, but even from Christians of all stripes … including ourselves. Over the next few weeks, we’re going to talk to some of the most prominent advocates of this controversial idea …. as well as to scientists who are the world experts in the areas on which those advocates build their pro-ID arguments. But before we do that, we thought we’d re-release an episode that we recorded three years ago, which introduces this controversial idea and sums up many of the reasons why we find it so hard to fully embrace it. Our main stopping points in the discussion included: why “Intelligent Design” is hard for Christians to resist: “we’re made/designed by God, and God would be intelligent” why we can’t embrace Intelligent Design: too many examples of design which are not just clumsy (the retina of our eye) or unclear to us (goose bumps; ability to wiggle our ears; fingernails), but even many which are just fundamentally wicked: the joining of our food-pipe and wind-pipe results in a horrible death for people who breath at the wrong time while swimming, or took too big a bite out of their sandwich, or who have Lou Gehrig’s disease (ALS), or gastric acid reflux leading to respiratory dysfunction; childbirth: without modern medicine, too many mothers and babies die a horrible and slow death through exhaustion from not being able to expel the baby, or slowly bleeding to death, or having the life slowly squeezed out. it’s awkward (to say the least!) to speak of a God who intervenes in our lives to give us beautiful design when there are these examples of horrible design, just like it’s hard to attribute good outcomes to an intervening God when horribly bad things happen to other people around us (like saying “God steered this tornado right around our house and saved us from destruction,” when that same tornado destroyed the neighbor’s house and killed his kids) those “horrible examples” are better explained by evolution working from the bottom-up and landing on solutions to a problem that work most of the time, than a carefully-considered design from the top-down we need more clarity and nuance around words like random, undirected, designed, and orchestrated genetic evolution does not only operate through small, incremental changes in the genetic code (which is as far as Intelligent Design advocates want to take this conversation); there are many other mechanisms that lead to sudden and big changes (many of which we talked about in detail with Dr. James Shapiro in Episode #70): gene duplication, with subsequent modification and selection pre-programmed gene shuffling and re-organization information inherited from the mother through machines inside the egg (the mitochondria) and molecules (glycoproteins) on the “skin” of the egg recombination of pairs of chromosomes “epigenetics” (this is an umbrella term which simply means everything that doesn’t involve genes”) even the writers of scripture, the ancient Hebrews, recognized childbirth as an argument against design, which is why they re-framed it as a punishment against breaking a Divine law. God can create using naturalistic mechanism (the Big Bang; chemical evolution; genetic evolution; natural selection) the “horrible examples” described above are not examples of previously good designs which were broken by the Fall in the Garden, as many Young Earth Creationists will propose; they are instead fundamental designs right from the start.

#129 – A new way to “do church”

“Why not just throw the worship service out the window, and re-think what it means to be a Christian community?” Most Christians today have nestled into, or hopped between, a very standard modern expression of Christian faith, one that involves meeting for an hour on Sunday and having an unchanging mixture of songs, scripture reading, announcements, sermon, and prayer. Many people are leaving churches, and even Christianity itself, because it just doesn’t meet their spiritual needs. Today, we talk to Dr. Evan Amo, who did theological training at Princeton Theological Seminary and after a few traditional conservative Christian pastoral placements, asked: “why not just throw the worship service out the window, and just re-think what it means to be a Christian community?” Here are the main points in our conversation of his spiritual journey and his own answer to that question: grew up in a typical mainline Presbyterian church with a traditional worship style that was beginning to experiment with “contemporary worship”; quite comfortable and satisfied in that setting and with those traditions; “inerrancy and ‘personal relationship’ was the default thinking there” went off to university which introduced him to a more critical approach to the Bible, and joined a different Evangelical church which was a bit less conservative; both began to challenge some of his theological upbringing also began developing musical skills; formed a band following his undergraduate degree, and some Christian leadership experience at a Christian camp, as well as “doors being closed” in his music career, Evan began graduate training at Princeton Theological Seminary never had aspirations for typical pastoral career, but wanted something “outside of the box”; theological interests started curving toward social justice and liberation theology; these were hugely influenced by socio-political upheavals in the U.S. at the time after graduating from Princeton, he served for two years in a large church in North Carolina; then moved on to a temporary supply pastor position in a nearby small rural — and very conservative — Presbyterian church; this help shaped his sensitivity toward, and abilities to speak to, people with a very different worldview served four years in a small aging African-American church in Denver, including the years of COVID and racial unrest in the U.S. most recently, he has started a whole new venture in Denver, supported by the Presbytery of Denver, one that is completely different in how it engages Christian faith; a spiritual community that combines worship in nature (meditation hikes) with social justice and compassion work with marginalized groups in the inner city; this includes people from other faith traditions (Catholic) and world religions (Judaism; Buddhism); also very connected to Celtic spirituality, and indigenous spirituality his vocation better addresses issues in the current Post-Christendom age (marked by a major disaffiliation of society from traditional church) church and state have traditionally been kept separate ….. Christian Nationalism seeks to reverse that; conservative Christians have nostalgia for a long-gone era …. feel threatened by on-going cultural and demographic changes in which white people become a minority our discussion of Celtic/indigenous spirituality led to a lot of exploration of panentheism in Christian thinking (including the Apostle Paul) which many contemporary Christians are either unaware of or they react strongly against that is there a disconnect between trying to worship God in a very natural setting (remember, Evan’s doing this in the Rocky Mountains of Denver) while engaging in inner city ministry? And for other cities which don’t have such natural beauty (the heart of Detroit) or don’t have “an inner city problem” (rural Idaho), how can they learn from and apply this new idea? Evan is also an accomplished musician, and gave us a lot of descriptive insights about his two albums (their inspiration; their meaning), and excerpts from several songs As always, tell us your thoughts on this topic … Find more information about Evan’s new way of “doing church” at their website or Instagram account, and his music at www.bruisedreeds.bandcamp.com.

#128 – Lessons learned from our listeners

Four particularly toxic ingredients make it especially hard for some (many?) Evangelicals to maintain their belief system beyond a few decades. Christianity, in the West at least, is certainly experiencing a “great falling away”: churches closing, memberships dropping, people leaving the faith entirely. Some might conclude they’re leaving in order to better enjoy “sex, drugs and rock and roll.” But a closer look reveals that their departure has so much more to do with simply being unable to hold on to something that just produces so much doubt, internal conflict, cognitive dissonance, and challenges to personal integrity. And a variety of forms of religious abuse have certainly helped people out the doors. We certainly found this to be the case for the four of our listeners whom we interviewed over the past four weeks. We learned that all four of them have rejected the form of Christian faith that they grew up with and held quite comfortably for a couple decades. Two of them no longer go to church at all, while a third one attends as an atheist. And none of them would again embrace the label “Evangelical.” But all four are still always listening, reading and talking about ….. Christian things. They’re still “scratching the itch”! In this episode, we distill some themes, commonalities, and lessons learned from those four conversations. Points that we covered include: the strange beliefs of their original Christian faith seemed to be so normal and acceptable at the time, but now they see moral atrocities, unscientific claims, philosophical paradoxes, and theological conflicts there are four “toxic ingredients” that need to be revised or gotten rid of: inerrancy and infallibility of scripture hell theology (esp. eternal conscious torment) Penal Substitution Christian exclusivism too many people don’t correctly understand in detail the origins of the Bible, and its human input inerrancy and infallibility is never mentioned in the Bible; Jesus often turned scripture upside-down; even people who claim to adhere completely to inerrancy/infallibility don’t take many parts of the Bible “literally” Peter Enns (episode #57) and Mark Elliott (episode #116) had no concerns about Luke’s claim that the Bible is more like a human diary or notebook, than a Divine dictation the origin of the doctrine of inerrancy/infallibility is very recent, and rooted in politics and religious control the origin of the Chicago Statement on Inerrancy and Infallibility what did Jesus mean by “not one least stroke of a pen will disappear from the Law before all these things are fulfilled”? This is often a proof text for people who defend inerrancy and infallibility for many people, Christianity is all about avoiding hell the great difficulty in believing God could be as brutal, judgmental, and vindictive as that Penal Substitution: the horrible idea that God just NEEDS to see blood spilled before he can forgive and forget, even the blood of someone who has nothing to do with the “crime” Christian exclusivism: that all other religions, and even many strands of Christianity, are on the wrong path and will find themselves in hell Evangelical Christianity has many beliefs that are equally “off-track” as any other world religion (the “prosperity Gospel”, Penal Substitution; Christian Nationalism; anti-gay/anti-trans Christianity) Jesus is the basis for salvation in the sense that he held up a model for us to follow that we need to strive for … the “Good News,” or Euangelion many atheists and adherents to other world religions are doing a better job of living out that Good News message than many Christians In addition to the four “toxic ingredients,” there’s another ingredient that may not be toxic, but is still very problematic … the ideal of having a “personal relationship” with the Divine does autism impair ones ability to experience a “personal relationship”? if one still finds value in the Bible and strives to follow the teachings of Christ, but drops those four toxic ingredients and the problematic one, is that still a truly Christian faith? Orthodoxy versus orthopraxy: showing one’s faith through their works … the parable of “the sheep and the goats” listener feedback on our FaceBook Discussion forum: Doug, Merv and Lori: “please give us more of these interviews …. we can relate to these people” Doug: Scott’s comment about nihilism being the next stopping point for those who give up Christian faith … finding ultimate meaning Mi K.: Christianity is not monolithic …. there are many forms which bear no resemblance to each other …. having problems with one form should not require rejecting all of them Nichola: “Evangelical” is a label which can’t be rehabilitated is the arc of Christianity approaching another inflection point? … will 21st century Christianity look as different from 20th century Christianity, as the latter looks from 10th century, or 5th century, or 1st century Christianities As always, tell us your thoughts on this topic … If you enjoyed this episode, you may also like Episode #14, where we first talked about four core problems with Evangelicalism. More specific points that we skimmed over were discussed in greater detail in episodes #19 (Penal Substitution), #42 (“personal relationship”), and #88 (Hell). Episode image from Pixabay.

#127 – Rachel’s spiritual journey

A traumatic experience while serving in a church led to a complete deconstruction of her Christian faith: she’s still “a hopeful Christian agnostic” who finds Jesus’ message “beautiful and life-giving” Another one of our listeners tells her story. Rachel Sanders also grew up in a conservative Evangelical home, and went to a Southern Baptist church, but it was her years in Christian elementary, middle and high schools, and then a Christian college which really instilled in her a Fundamentalist Christian worldview. For a couple decades, she was quite comfortable in that faith system; doubts and questions rumbled in the distance, but she was able to keep the cognitive dissonance suppressed. Until she and her partner began ministry work in a church out of state. An escalating series of clashes and confrontations with members of the congregation and the pastor led them to not only leave that church, but then triggered a full theological deconstruction. That storm shipwrecked her faith! She now calls herself a “hopeful Christian agnostic,” because she still finds the message of Christ to be beautiful and life-giving. But for now, returning to a church, even as just a pew-warmer, is out of the question. Some of the points we talked about with Rachel include: parents were divorced from her earliest memory step father had been a Baptist minister, but his ordination was removed because he married a divorcee grew up in a large Southern Baptist church; very conservative; attended a Fundamentalist Christian elementary school, and then private Christian high school; Bible classes taught them Young Earth Creationism, Purity Culture; evolution is a “theory without much evidence”; “accepted Jesus into her life” at age of five …. “did I understand what Jesus was saving me from, I don’t know”; fully embraced her early Christian Faith; happy to have a guidebook for her life her faith was purely intellectual during elementary school years, but more on an emotional level when in her teens; the lack of emotional investment prompted a crisis-of-faith huge personal impact of a missions trip to Haiti went to Asbury College (recently in the news for its “revival”), where she developed a Wesleyan tradition the “slippery slope” … “well, if this part of the Bible isn’t “true”, then what about that part?” was not taught about a literal/historical Adam and Eve, but isn’t sure what they did with Original Sin has long been conflicted with their teaching about hell; wondered “what’s the point of Christianity if there is no hell?” “the sermon-cycle of shame and regret” and “thought-terminating cliches” her deconstruction process was catalyzed/accelerated by the political unrest of the past few years for years, got comfortable with cognitive dissonance over theological problems; but abuse and betrayal by her church community tipped her over the edge a traumatic experience with a senior church ministry leader crystallized the ending of her faith; she and her partner left church behind them connected on-line with other people who had been hurt by the church, and that fueled the deconstruction of her theology still looking for a church that hasn’t weaponized the Bible still holds a faith in a creative Life Force … calls herself “a hopeful agnostic Christian”; still attracted to Christ, and his message Scott asks if nihilism is the next step the label “Evangelical” has been hijacked, and we need to recover its original meaning Christianity is so much more broadly based than just “Evangelical” Christianity; need to explore its full dimensions before rejecting the whole theology it’s OK to not know … there’s freedom in mystery As always, tell us your thoughts on this topic … If you’re interested in other personal life stories of people we’ve interviewed, check out this thematic collection.
